Father Zed is running a story which says that the SSPX could be reconciled by Monday, as their reconcilliation has been one of Benedict's main concerns fopr the last 30 years, presumably some legal/theological package is on a desk somewhere.
Last year Bishop Fellay suggested that the SSPX's relationship with Rome could be like that of the Chinese Patriotic Church, which is interesting, and presumably indicates a degree of autonomy, we will see.
I was speaking to a priest the other day, who was quite angry about the likely reconciliation, which was quite sad, especially as he had been heavily involved with ARCIC on a local level. I think he fails, like many people, to understand the Pope's priorities.
I see them as being twofold:
The Reconciliation of East and West, in a sense the bringing into communion of the SSPX and other traditional groups, as well as the Anglican group TAC is both a model for the East and an "experiment" in plurality for the West.
The Reconciliation of the Catholic Church with its history, a substantial part of this is the great battle with "relativism" and overthrowing the notion of the "Spirit of Council". John Paul II in Et Unum Sint said the role of the Pope is the great obstacle to unity. In his writings the Pope Benedict sees the bishops as being the "faithful bearers of the Tradition" they are supposed to be overseers and regulators of the Church. It is only when bishops are unable to do this that there is a need for a strong Papacy.
Benedict realises that he will die before either of these are achieved but what he seems to be doing is laying a foundation to a renewed and authentic Catholic ecclessiology that a successor will find impossible to undo.
